Method for raising sunken ships

ABSTRACT

The object of the utility model is a method of raising the sunken ships. Its application is a ship salvage. The essence of the utility model is that with the help of divers the sealed deflated balloons, with the containers filled with carbon dioxide or other gas attached inside of them, are placed in the compartments with water. The container with the gas inside the balloon is triggered by using a radio signal, which is supplied by the divers from the surface and fills the balloon. Technical result is achieved in improving and increasing the efficiency of raising the sunken ships, compliant with the modem requirements and low material costs.

The present application is a National Stage application of PCT application No.PCT/UA2013/000041 filed on Apr. 11, 2013, which claims priority to Ukranian application No. u201209188 filed Jul. 26, 2012.

The invention relates to the techniques for salvaging works and can be used for raising sunken ships (and their parts), and other objects out of the water or from the bottom of the ocean or sea or lake.

Salvaging works are unique. Their implementation requires special tools and equipment. In addition, each new work is not similar to the previous one.

The closest to the proposed method, and therefore the one that we have adopted as a prototype, is a method for lifting the sunken ship and the device for its implementation, which includes fixing ties, invaders, pipelines, tanks, filling them with gas, and using buoyancy force. The principle of the method is the following: the reservoir system, which is filled with water, is moved down and fixed to the right end with the subsequent dewatering and filling with gas first, and then the reservoir system, which is filled with water, is moved down and fixed to the left end, followed by pumping out the water and filling it with gas.

(UA); applicant and patentee Timofeev M. I., Liviiskii A. M., Bondarenko E. V. (UA)—no. 2001010691; claimed 30 Jan. 2001; published 15 May2001).

The disadvantages of the chosen prototype are a rather complicated structure and a process of technical implementation, as well as a relatively high cost.

The basis of the utility model is aimed at providing a better way to raise the sunken ships by placing in the compartments with water, depending on their square area, deflated sealed balls Inside of the deflated sealed balls there are fixed cylinders with carbon dioxide, and that the gas from a cylinder goes to the ball via radio signal, which is supplied from the surface. This result to the displacement of water from the compartments, thereby making the ship easier to lift; and the gas in the balloons, in turn, has the lift force, while using the buoyant force, which ensures the lifting of ship to the surface.

The essence of the utility model is that with the help of divers, the sealed deflated balloons, with the cylinders with carbon dioxide or other gas attached inside of them, are placed in the compartments with water. The container with the gas inside the balloon is triggered by using a radio signal. That signal is supplied by the divers from the surface and fills the balloon.

The technical result of the proposed method is simplicity of its implementation and improving of the efficiency of raising sunken ships, due to the lifting power of the gas in the balloons. In turn, the balls which are filled with gas, push the water out of the compartments of the ship, allowing to raise the sunken ship to the surface, without using the additional equipment. This method corresponds to the modern requirements, does not require high material costs for its implementation. The balls are intended to be reusable.

Thus, the proposed utility model can improve the way of raising the sunken ships.

The method is as follows.

The divers, depending on the square area of water-filled compartments, place the sealed balls, deflated and folded to the smallest size, inside of which there is a fixed cylinder, containing the carbon dioxide or other gas, which is triggered by a radio signal and inflates the balloon. After using, the balloon is blown off through the descent valve, after that it can be reused.

The given method can be used as a main one or as an auxiliary one, while lifting the sunken ship. 

1. A method of raising a sunken ship by using the buoyancy force of containers, attached to the ship, comprising: placing sealed deflated balloons with containers with a gas, attached inside, in ship compartments filled with water, where the containers fill the balloons with the has after receiving a remote signal.
 2. The method of claim 1, wherein the gas is carbon dioxide,
 3. The method of claim 1, wherein the signal is sent from a surface above a sea level.
 4. The method of claim 1, wherein the signal is a radio signal.
